I took the advice and achieved next to nothing.
The score is that my daughter's "upteen-thousand dollars Mac" has no
problems in finding and reading the content of my ($2.00) SD-Card
reader. My computer - even with the help of the usb-hub - cannot find
it. The red light on the plugged-in SD-Card reader is on, but there is
no trace of it under the /media directory. And I do not know where else
to look.
The second output of dmesg (attached) remained unchanged when I ran the
"mount" command. However, my computer was not able to read the contents
of the "memory stick" until it received the "mount" command.
Buying a new computer seems a drastic remedy?
